15x8 w/ 4.5” BS on front/good handling size?

Thanks for the input everyone. Sounds like I need to get measuring. Wheel choices are super limited seems like they never have enough backspace.
I'm curious. Why do you think 15x7 with 4" backspace WONT work? I thought that was a fairly universal fits-everything wheel.
And, what style of wheel are you looking for? Slots? Lightweight wheels to match the rears, only wider? Steelies? Five spoke?
More info please.
